INSULATOR FOR ELECTRIC CONDUCTORS.

SPECIFICATION forming part of Letters Patent No. 440,042, dated November 4, 1890.

Application filed August 8, 1890,

T0 aZZ whom it may concern:

Be it known that I, TILLIAM KEssLER, a citizen of the United States, residing at Lafayette, in the county of Tippecanoe and State of Indiana, have invented a new and useful Insulator for Electric Conductors, of which the following is a specification.

The invention relates to improvements in insulators for electric conductors.

The object of the present invention is to simplify the manner of attaching wires to insulators and to provide an insulator adapted to receive and securely retain a wire without necessitating the usual tying.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter fully described, and illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of an insulator constructed in accordance with this invention. Figs. 2 and 3 are similar views of the sections. Fig. 4 is a central longitudinal sectional view. Fig. 5 is a similar view illustrating the sections reversed and adapted to receive a pair of wires.

Referring to the accompanying drawings, 1 and 2 designate sections of a cylindrical insulator constructed of glass, porcelai n, or similar insulating material and being cylindrical in form and provided with a central longitudinal opening 3,adapted to receive a screw, nail, or the like forattaching the insulator to asuitable supporting-surface and for securing the sections together and clamping between them a wire or wires. The sections 1 and 2 are cylindrical, and the former is provided in its face 4 with a transverse groove 5, adapted to receive Serial No. 361,453. (No model.)

and have iit within a similarly-disposed rib 6 of the section 2. The rib and groove of the faces 4 and 7 prevent the sections turning on each other and injuring the insulation of wire, which is arranged in transverse grooves 8 and 9, located at one side of the rib and groove and extending parallel therewith, and the said grooves S and 9 are adapted to be arranged opposite each other to form a cylindrical opening for the reception of a wire, or the sections may be reversed to arrange the grooves upon opposite sides of the rib and groove to enable the insulator to receive a pair of wires.

It will be seen that the insulator is simple and inexpensive and is adapted to receive a single wire or a pair of wires, and there is no liability of injuring the insulation of the wires.

What I claim is A cylindrical insulator provided with a central longitudinal opening and composed of a cylindrical section 1, provided in its face 4 with a transverse groove 5, a groove 8, arranged parallel with the groove 5, and a similar section 2, provided with a central rib 6, adapted to fit in the groove 5, and having a groove 9 arranged parallel'with the rib, said section 2 being reversible to provide a wire groove on one or both sides of the insulator, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
